Omnidirectional Antenna  (150-1618)    Installation    Faxback Doc. # 6815

INSTALLING F-CONNECTORS ON COAX CABLE

Step 1:  Strip the outer cover back 1/2-inch from the end of the cable.
         Fold the braid back as far as the outer cover allows.

Step 2:  Trim the braid close to the outer cover and remove 1/4-inch of
         inner insulation being careful not to nick the center 
         conductor.  Make sure no foil or braid can touch the center
         conductor.

Step 3:  Slide the connector tip between the braid and the inner
         insulation (or the braid and the foil, on foil-shield cable)
         and push the connector onto the cable as far as it will go.
         Crimp built-in ferrule with the proper crimping tool.  
         Connectors with extended ferrule require a hex crimping tool.
         Do not crush cable out-of-round.
         IF INSTALLING IN VERY HOT WEATHER, INCREASE THE DIMENSIONS BY 
         1/8-INCH.

ANTENNA MOUNTING INSTRUCTIONS

NOTE:  For best results, mount the antenna away from trees or other 
       obstructions.  Higher frequencies are noticeably affected by
       these obstructions.

STEP 1:

Outdoor Installation:

Attach the mounting bracket to the bottom of the antenna as shown and
mount the antenna on the mast.  Tighten the U-bolts.  Connect the downlead
to the jack in the antenna, and slide the weather boot over the boot
collar.  If the cable does not have a weather boot, seal the connection
with coax sealant tape.

Indoor Installation:

You can mount the antenna in an attic, closet, or other out-of-the way, 
indoor location.  Mount the antenna on a short piece of mast suspended
from a roof support by a 4-inch wall-mount bracket (Cat. No. 15-883).

In a closet, you can similarly attach the antenna to a section of the mast
or simply place the antenna on a shelf.  Be sure the antenna is not in a
position where it would easily fall or otherwise be damaged.

STEP 2: 

In a convenient location mount the two #6 screws vertically 3 1/4-inches
apart leaving the screw heads approximately 1/8-inch from wall.  Hang
power supply onto screws.

Step 3:

Connect the downlead to the TO PREAMP jack on the power supply.  Do not
install splitters between the power supply and antenna.

Step 4:

Attach the connector end of the cable from the TV to the TO TV jack on the
power supply.

RECOMMENDATIONS FOR INSTALLING COAX CABLE

      Minimum Bending Radius:  (RG-6/U type) 3-inch radius.  Tighter bends
                               cause shorts and change impedance.

             Pulling Tension:  75 pounds maximum.  Leave no tension on the
                               cable after it is installed.

           Staples or Clamps:  Using flat staples with coax cable damages
                               the cable.  You should use only round-
                               headed staples.  Any clamps or securing
                               devices used with coax should grip the
                               cable evenly about the circumference
                               without crushing the cable.

Exposure to High Temperature:  Maximum temperature limit 176 degrees F (80
                               degrees C).  Keep the cable away from
                               heating vents and water heaters.

                    Crushing:  You should not install coax in a manner
                               that would let it be crushed.  The coax
                               should not be stuffed or wedged into areas
                               where the cable could be pinched.

        Exposure to Moisture:  The cable jacket withstands most outdoor
                               environments.  However, you must seal
                               connections and splices against water
                               entry.

HOW TO PROVIDE LIGHTNING PROTECTION FOR THE TV ANTENNA AND SET
(For outside mount)

Mount a grounding block, such as Radio Shack Cat. No. 15-909, as close as
possible to where the downlead enters the house.

Ground wires for both the mast and downlead should be copper or aluminum
wire, #8 or larger.

Downlead wire from the antenna to the grounding block and the mast ground
wire should be secured to the house with stand-off insulators, spaced from
four to six feet apart.

For a "ground up" antenna installation, you might not need to ground the
mast if the mast extends four or more feet into the earth.
